This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Personio operates in the technology sector providing SaaS HR solutions for companies with 10 to 5,000 employees. Its business model focuses on subscription-based software services with a strong emphasis on integration capabilities and professional support. The company maintains a consistent brand image and targets a broad SME market across multiple European countries, as evidenced by multilingual site versions. The presence of a marketplace and support domains indicates a mature ecosystem and customer engagement strategy. The lack of direct contact details on the main site suggests a focus on digital self-service and lead generation via demos and trials.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and use of a consent management platform for GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response contact limits transparency in security governance. There is no visible vulnerability disclosure or security.txt file, which could be improved to enhance trust and facilitate responsible vulnerability reporting. Overall, the security posture is strong but could benefit from more explicit security documentation.

Recommendations

  1. Publish a dedicated privacy policy page with clear GDPR compliance details.
  2. Add terms of service and security policy pages accessible from the main navigation or footer.
  3. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  4. Implement and publish a vulnerability disclosure policy or security.txt file.
  5. Enhance contact information availability to improve customer trust and support accessibility.

Technical notes

Notes

The website uses a modern React and Next.js stack, optimized for performance and mobile responsiveness. It employs advanced techniques such as Lottie animations and WebP images for efficient media delivery. Hosting appears to be on Vercel, supported by the presence of Vercel Speed Insights scripts. The site integrates multiple third-party services including Usercentrics for consent management, Google Tag Manager for analytics, and Visual Website Optimizer for A/B testing. The technical implementation is robust with good SEO and accessibility practices. There is minimal technical debt visible, and the site is well-structured for scalability and maintainability.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
